A 33,000-year-old skull of a "wolf on the way to becoming a dog" was found in a Siberian cave. Evolutionary Biologist Susan Crockford, co-author of a study about the skull in PLoS ONE, discusses why the discovery challenges common beliefs about dog domestication.
In his book, Reinventing Discovery: The New Era of Networked Science, Physicist Michael Nielsen discusses why scientists jealously guard their data and are slow to adopt online tools for collaboration. Nielsen talks about why attempts to create science wikipedias have failed.
This is SCIENCE FRIDAY. I'm Ira Flatow. Stem cell therapy, it seems, is always promising, promising to cure diseases or illnesses. And this week, a study using embryonic stem cells has increased the hope of fulfilling some of those promises.
Time now for our Video Pick of the Week. Flora Lichtman, our multimedia editor is here. Hi, Flora.
FLORA LICHTMAN, BYLINE: Hi, Ira.
FLATOW: Good video as always.
(SOUNDBITE OF LAUGHTER)
LICHTMAN: Yeah. This one is about something that I encounter every day, and I think of it as little more than a beverage cooler or maybe a nuisance on my commute to work. I'm talking about ice. But it turns out that ice was way more interesting than I knew before (unintelligible)...
Glory Ndudi, a Christian, and her five children board a bus headed out of town on Wednesday. The recent bomb attacks that have targeted churches in Kano, Nigeria, have led to an exodus of Christians from the city.

But a federal investigation finds that the department's programs are so disorganized that it's difficult to figure out how the money has been spent.

R&B icon Betty Wright signed her first local label deal when she was only 11, and by the time she was 17, she'd released her first hit single, 1971's "Clean Up Woman," which also crossed over to the pop charts.

For more than a decade, Republican presidential candidate Ron Paul has had to deal with questions about why a newsletter he published in the 1980s and '90s included some racist writings.

In election season, conventional wisdom holds that a costly, drawn-out primary fight hurts a nominee in the general election.
It's a notion that appeals to common sense. After all, the thinking goes, if a boxer endures nine rounds with a formidable challenger and immediately steps back into the ring with a well-rested heavyweight, that can't be good.
